SPECIFICATION forming part of Letters Patent No. 755,998, dated March 29, 1904. Application filed Jluly 6, 1903. Serial No. 164,258. (No model.)

To all whom t may concern:

Be it known that I, EDGAR CHAMBERS, a citi- Zen of the United States, residing in Meriden, in the county of N ewHaven and State of Connecticut, have invented certain new and useful Improvements in Tempering and Coloring .Apparatus of which the following is a specication. Y

This invention relates to and has for an object to provide an improved tempering and coloring apparatus, and particularly the driving means therefor.

A Heretofore in tempering and coloring small articlesmsuch as pen points, clock `hands,

screws, and the like-the articles have been placed in a metallic. barrel supported above some source of heat-a charcoal fire or a flameand the barrel rotated byl means of a handcrank fast to .the barrel, and at the arrival of lthe lproper temperature the barrel was removed from the lfurnace and its contents thrown out upon a tray. This necessitated A the constant attention of one man to turn the barrel and the assistance of another man when it came time to empty the barrel. It has not heretofore been found possible t'o rotate the Owing to the fact that when the critical point arrives the barrel must be instantly withdrawn from the heatA and the work agitated up to the instant of such withdrawal, any delay to uncouple driving mechanism would be disastrous to the work. Inmy device, however, the barrel is supported above the furnace and mechanically rotated in such manner that it may be raised from the furnace, as heretofore, without any unlocking of fastening devices. The barrel carries mechanism which will engage driving mechanism supported by the furnace when it is placed above the furnace and may be withdrawn from such driving means upon the furnace by merely raising the barrel and without unfastening or uncou'pling such driving mechanism further than the disengagement of -the parts of the driving mechanism while one part is moved from the other as it follows the movement of the barrel and the parts break f engagement. This may be accomplished by away. Fig. 2 is an end View, and Fig. 3 is a tail, of the driver.

The barrel is intended for ready removal from the furnace, and the driving-gear must be so located that the barrel may be easily re moved from the furnace by hand, and owing to the fact that it is to` be removed by hand the .weight added to the same by the presence of the cog-wheel .must be so distributed that it will be possible for a workman to lift the barrel. When he grasps the shaft to raise the barrel from the furnace, he must take hold of thesame near the barrel with one hand, so that he ,can apply his strength to the best advantage. Were the cog-wheel ina position toV engage driving-cogs outside of the furnace it would bring such `cog-wheel to a position upon the shaft where it would interfere with him. grasping the same near the bardiffculty that a barrel could be handled in the manner required in this art. This Ainvention therefore presents not only the feature of having the gearing where it will not interfere with the action of the barrel in being raised from the furnace, but also in a position where it will not throw additional and unnecessary work upon the operator.

The furnace (designated in a general way by 4) is herein shown as embodying a box having sides 5 and ends 6, supported by legs 7 and having some heating device within it, in the present instance shown as an aeratedgas burner 8, coupled to a pipe 9 in communication with pipes Y1'() and ll for supplying fuel and air to the burners. Flames 12 are represented as emitted from the burners. The articles to vbe treated will be placed within a barrel 13, which is shown as having side walls 14,

TOO

` side walls.

a breast 15, and a neck 16, reduced in size in the present instance as compared with the The barrel is also provided with a suitable bottom 17. One end of the box or furnace is shown as provided with a pair of stub-shafts 18, each supporting an antifriction roller or sheave 19 for supporting the neck of the barrel. The other end of the box carries stub-shafts 20, each supporting an antifriction roll or sheave 2l. A spider 22 is bolted to the bottom of the barrel and has projecting therefrom a shaft 23, which is supported by the rolls or sheaves 21. A cogwheel 24 is shown as fast upon the shaft adjacent to the bottom of the barrel, and when the barrel is in position upon the rolls or sheaves such cog-wheel will be within the furnace-box, but adjacent to one end thereof, which end supports a bracket 25, having a bearing 26 for a shaft 27, carrying at one end a pinion 28 within the box and in position to mesh with the cog-wheel 24 when the barrel is in place resting upon the rolls or sheaves. The shaft 27 carries a pulley 29, driven from some suitable source of power. (Not shown.) For the purpose of steadying and guiding the cog-wheel an idle pinion 30 is shown as supported by a stub-shaft 31, carried by a bracket 32 upon the end of the furnace-box.

The shaft 23 not only serves the function of a shaft, but also that of a handle for the manipulation ofthe barrel.

Assuming the fire in the furnace to be at the desired temperature, the articles which it is desired to temper or to otherwise treat by heat will be placed within the barrel and the neck of the barrel allowed to rest upon the rolls or sheaves 19. The cog-wheel will then be brought into gear with the idler 30, when by a slight movement it may be brought into mesh with the driving pinion 28 without shock or stripping of cogs. .The attendant may then leave the barrel and go about other work, as his duties demand, returning at the proper time to remove the barrel from the furnace, which will be done instantly upon ascertaining that the desired temperature or color has been imparted to the work. This may be done without throwing olf belting or unfastening or uncoupling any of the driving mechanism.

The additional weight of the driving cogwheel 24 is so placed that it will come near the operators hand, giving him the greatest amount of leverage in its actuation, and at such a position that it will not catch or interfere with any portion of the furnace.

It will be apparent that changes may be made in the structure as the various employments to which it may beladapted will demand without departing from the spirit of my invention.

Having described my invention, I claim-- 1. The combination with a furnace, of a pair of sheaves at each end of the furnace; a barrel having a mouth surrounded by walls adapted to rest upon a pair of said sheaves; a handle extending from the end of the barrel opposite the mouthto rest upon the other pair of sheaves and adapted for the manual lifting of the barrel from the furnace; a cog-wheel fast upon the handle near the barrel and between it and the point of engagementwith the sheaves; a pair of pinions imide of the furnace and below the sheaves and adapted to mesh with such cog-wheel inside of thc furnace; and means to drive one of said pinions.
